URecruit market notes (2024–2025 hiring)

• 4-on-4-off and continental shifts continue to price in night/rota premiums.
• HVAP capabilities and incident leadership are the clearest pay levers at mid-senior.
• Network depth (CCNA→CCNP, NX-OS/BGP/OSPF) + cloud adjacency (AWS/Azure) = interview fast-track in London/South East builds.

Use this as a baseline—then adjust for shifts, HV/AP, clearance, and on-call.
Where sample sizes are small (e.g., Scotland DC Engineer), triangulate with local employer data.

What Moves Pay Up (or Down)

• Shift pattern: 4-on-4-off and nights carry built-in premiums vs days.
• HV/AP authorisation: HV switching, SAP responsibility, and LOTO competence materially increase base and OTE.
• Critical facilities exposure: Tier III/IV sites with strict SLAs tend to pay more than single-tenant server rooms.
• Network depth: Hands-on NX-OS/BGP/OSPF, firewalls, and DC fabric skills add leverage beyond general ops.
• Cloud adjacency: Touchpoints with AWS/Azure/Direct Connect/ExpressRoute boost interview rates.
• Security clearance: Sites with SC/NPPV clearances add a premium and reduce candidate pools.

Certification Premiums (real ranges you'll see)

High Voltage Authorised Person (HVAP / SAP):

• Shift Lead HVAP: £51,000–£61,000 base typical.
• Day Technician + HVAP allowance: up to ~£52,000 + allowance.
• Shift Engineer (HVAP): £56,000–£58,000 common band.

Networking (CCNA → CCNP):

• CCNP correlates with higher offers vs general admin roles.
• Treat global CCNP pay pages as directional; UK mid bands commonly £55k–£70k where CCNP maps to DC fabric work.

Data Centre-specific certifications:

• CDCP (Certified Data Centre Professional): entry standard for many colocation operators; 3-year validity.
• CDCDP (Design Professional): advanced design; typically used by design/build or consultancy.
• CDCMP (Management Professional): ops leadership focus.
• Uptime Institute ATD/ATS: premium Tier design/operations credentials favoured by enterprise and hyperscale clients.
